1 Claim.

This invention appertains to new and useful improvements in unloaders and more'especially to grain unloaders for various kinds of grain vehicles. Y

An important objectof the present invention is to provide an unloader which will require very limited space 'and which in operation will be of quick action yet not susceptible to the ready development of defects.

lo Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Flgure 1 represents a fragmentary vertical sec- 15 tional view through the vehicle and unloader.

Figure 2 is a fragmentary vertical transverse sectional view through the unloader.

Referring' to the drawings `Jvherein like numerals designate like parts, it can be seen that 2o numeral 5 represents the grain box of the vehicle which includes the bottom 6, having the removable closure 1. Numeral 8 denotes the conduit which underlies the bottom 6 and which is pro'- vided with a short upstanding spout 9 disposed into the wall structure I0 which underlies the bottom 8 at the aforementioned discharge opening.

The forward end of the conduit 8 is closed and through this extends the shaft Il which carries 30 the feed screw I2.

Numeral I3 represents the vertical chute ,which is provided with'a horizontally disposed annular wall I4 embracing the rear end of the conduit 8 for receiving grain discharged from the conduit l by the screw I2. 4

The rear end of the shaft .Il operates the sprocket wheel I 5 which has the pintle extension I8 operating through the` back wall a of the chute Il. ,A shaft I'I extends horizontally through the.

upper portion of the chute I3 and carries the 4 sprocket wheel I8. Over these sprocket wheels I! and IB is trained the endless sprocket chain I9 which carries the ,lifting plates 20 for the grain.

(Cl. 214-83) i These lifting plates are of a size which will barely pass vertically between the front and rear walls of the chute I3 and between the vertical partition 2l and the side wall 22.

A spout 23 suitably connected as at 24 to the off chute 25 serves to deliver grain to a point of deposit.

Ear 'members 26 are provided on the side wall oi' the chute I3 and through this is disposed the arm or bracket member 21 for supporting the chute and a suitable detent 28 (see Figure 1) may be used in conjunction therewith.

To keep the chute |43 against the back of the box 5, hook members 28--28'swingab1y connected to the box 5 can be hooked over eyes 29 on the 15 chute I3. Obviously, the chute I3v can be easily disconnected from the box and from the conduit 8 4and. can be used only (if desired) when grain is to be unloaded from the vehicle.

W'hile the foregoing specification sets forth the invention in specific terms, it is to be understoodthat numerous changes in the shape, size and materials may be resortedto without departing from the spirit and scope of the invention 'as claimed hereinafter.

Having described theinvention, what is claimed 25 A grain vehicle comprising a grain container having a discharge opening inthe bottom thereof, a conduit underlying the container and being in communication with the `interior of the container by way of the discharge opening, feed means in the conduit,'an elevator at the rear of the cpntainer, saidelevator .including a casing, detachable connecting means between the container and the casing, the lower portion of the elevator casing being provided with a sleeve-like extension `for slip connection with the adjacent end ci the conduit, and detachable coupling means between the feed means and the conduit and the lower portion of the said elevator.
